valve plates or disks are supported pivotally at points below-the; valve 'seatand as a result of/.this arrangement the valves `move more quickly to the sidejof the seat than is the casein previously used devices vWhere the valves arepivoted abovefthe 'seat' or'on the seat', This feature ef improved; valve gives a vastly increased open space through which the water may flow so that the ca-` pacity of the valve is much greater than in prior devices. t is further to be noted that in my present construction itis not necessary to machine any parts and no gaskets between the valve body and the strainer are needed inasmuch as the valve seat is integral with and on the inner side ofthe valve body or casing. It is not' necessary to, breakany joints when renewing the leathersior other packing on the valve disks or plates inasmuch as the valve is accessible from the bottom, if the strainer be removed, and itis necessary merely to remove the few small bolts by which'the valve disks are held together. ln assembling the'valves, the sector shape of the openings is advantageous inasmuch as the upper valve plate oi' disk is inserted through said opening with its lesser dimensionpresented to the .length of the opening so that 'it is easilyinserted therethrough and then turned to rest upon the lower plate.V

The Vforinof the invention shown in Figs.

' 4 and 5 differs from the form shown Ain Figs.

1,2'and3 andpreviously described mainlyV inemploying a single valve disk instead of two'va'lve disks. In`-these figures, the valve casing 2O is of thesame general form as the first described-valvecasing and may be secured to the suction tube of the pump in any desired manner. At 'the lower end of the casing 20 is an integral inwardly projecting n rhaving an inwardly projecting valve seat at valve seat 2l' having an elliptical or oval opening 22 formed therethrough. On the underside ofthe valve seat are lugs or ears 23 constituting hinge members and also channel lugsQll corresponding in all respects to the lugs l13 in the previously described form. Bolts 25 are carried by these channel lugs and serveto secure Vthe strainer 26 to the valvercasing. The valve coinprises'a lower plate 27' formed integral with a curved arm S'eXtending 'downwardlyand outwardlv and terminating in a hinge sleeve or hub member 29 disposed between thelugs 23 and suspended thereon by a pintle or pivot pin 30 inserted therethrough. The valve is com- [pletedl by a disk or plate 3l ofelliptical or oval outline to rest upon the seat 21 and secured to the vplate 27 by* bolts 32, a packing or facing 33 of leather or other suitable materialbeinginterposed between the plates 27 and 3l. vThe operation of lthis embodiment .i
